Limits on sending messages

There are several safeguards in place to make sure that only iCloud members can send messages using iCloud. One of these safeguards includes reasonable limits on:

The total number of messages you can send each day (1000 messages)

The number of recipients you can message each day (1000 recipients)

The maximum number of recipients per message (500 recipients)

The size of incoming and outgoing messages (20MB, up to 5GB with Mail Drop turned on)

iCloud Mail service is designed primarily for personal use. Sending unsolicited bulk email messages through iCloud email servers is prohibited. To review the iCloud membership agreement and acceptable use policy, please see the iCloud terms and conditions.

When you exceed message sending limits, you might see the following alert messages depending on how you view iCloud Mail:

On your iPhone, iPad, or iPod touch: A copy has been placed in your Outbox. Sending the message failed because you exceeded your sending limit.
